Build your own antenna rotator/satellite tracking device

Arduino Team — December 5th, 2017

After finding that purchasing a tracking device for his satellite dish would be quite expensive, YouTuber “Tysonpower” decided to simply build one himself. What he came up is an assembly made with 3D-printed parts and extruded aluminum that uses a pair of NEMA23 stepper motors for movement.

While it doesn’t quite work with the dish itself due to its offset weight, the concept was successfully used to track weather satellites using a VHF Yagi antenna.
